Subject: [PATCH] drm/i915: Add some more tracked state to intel_pipe_wm
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

intel_pipe_wm will be used to track the state in different stages
of the watermark update process. For that we need to keep a bit
more state in intel_pipe_wm.

We also need to separate the multi-pipe intel_wm_config computation
from ilk_compute_wm_parameters() as that one deals with the future
state, and we need the intel_wm_config to match the current hardware
state at the time we do the watermark merging for multiple pipes.
